Yuav ua li cas kho lub tshuab hluav taws xob uas tsis tsim hluav taws xob tom qab tau siv hluav taws xob
Muaj ob qhov xwm txheej uas lub tshuab hluav taws xob hluav taws xob tsis ua kom sov tom qab siv hluav taws xob. Ib qho yog tias nws tsis ua kom sov txhua lub sijhawm tom qab tau txais lub zog, uas tej zaum yuav yog vim kev puas tsuaj rau cov tub ntxhais hlau los yog lub hwj chim qaum. Lub sijhawm no, lub tshuab hluav taws xob digital tuaj yeem siv los ntsuas qhov kev tiv thaiv ntawm cov plugs ntawm cov hlua hluav taws xob hlau. Feem ntau, qhov kev ua haujlwm ntawm cov hlau ib txwm muaj nyob nruab nrab ntawm 110 ohms txog 12 kiloohms (qhov siab dua lub zog ntawm cov hlau soldering, qhov me dua qhov ntsuas tsis kam). Yog tias qhov ntsuas tsis muaj qhov ntsuas tsis kawg, nws yuav yog vim kev puas tsuaj rau cov tub ntxhais hlau los yog lub hwj chim qaum. Tsuas yog hloov cov tub ntxhais hlau los yog lub hwj chim qaum.
Yog hais tias cov hluav taws xob soldering hlau tseem kub me ntsis rau ib lub sij hawm ntev tom qab lub hwj chim thiab tsis tuaj yeem yaj lub solder hlau, nws yuav yog vim muaj ib tug tuab oxide txheej txuas rau sab hauv phab ntsa ntawm lub taub hau soldering hlau, uas cuam tshuam cov cua sov hloov ntawm lub taub hau. soldering hlau core rau soldering hlau taub hau. Qee qhov pheej yig hluav taws xob soldering irons tsis muaj qhov hloov kho qhov kub thiab txias ua haujlwm, thiab siv lub taub hau tooj liab soldering hlau pom hauv daim duab saum toj no. Yog tias cua sov rau lub sijhawm ntev, lub taub hau tooj liab yog qhov ua rau oxidation ntawm qhov kub thiab txias, ua rau lub siab thermal kuj oxide uas adheres rau sab hauv phab ntsa ntawm lub taub hau hlau soldering, ua rau cov cua sov tsim los ntawm cov tub ntxhais hlau soldering tsis tuaj yeem. kom kis tau mus rau lub taub hau hlau soldering ib txwm, yog li tiv thaiv lub melting ntawm cov hlau soldering.
Yog hais tias lub taub hau hlau yog oxidized hnyav heev thiab tsis tuaj yeem welded kom zoo, nws raug nquahu kom hloov nws nrog qhov zoo dua thiab kho tau qhov kub thiab txias hluav taws xob, vim qhov zoo ntawm cov hlau soldering muaj qhov cuam tshuam loj rau qhov vuam zoo. Qhov kub adjustable hluav taws xob soldering hlau qhia nyob rau hauv daim duab saum toj no yog luv nqi ntawm tsuas yog 20 yuan. Nws muaj qhov hloov kho qhov kub thiab txias thiab lub taub hau ntawm lub taub hau yog ua los ntawm cov hlau, uas tsis yooj yim rau oxidize thiab dub ntawm qhov kub thiab txias, ua rau nws yooj yim heev rau siv.
Lub tshuab hluav taws xob hluav taws xob yog tsim los ntawm ntau qhov chaw, suav nrog lub taub hau hlau, lub taub hau hlau, lub plhaub hlau, lub rooj ntoo (yas) kov, xaim xaim, thiab lub zog qaum. Lub tshav kub ntawm cov hlau soldering yog cov tub ntxhais hlau soldering ntsia rau ntawm lub taub hau. Ntev npaum li cov tub ntxhais hlau soldering yog siv rau, nws tuaj yeem ua haujlwm ib txwm.
Yog tias cov hlau tsis kub, thawj kauj ruam yog siv lub multimeter los ntsuas qhov tsis kam ntawm ob tus pins ntawm lub hwj chim ntsaws. Raws li ib txwm muaj, tus nqi kuj yuav tsum nyob nruab nrab ntawm ob peb puas mus rau ntau txhiab ohms. Yog tias nws nyob hauv lub xeev qhib, koj yuav tsum qhib lub kov los xyuas seb cov xov hlau puas ruaj khov thiab txhim khu kev qha. Tom qab ntawd ntsuas cov kab hluav taws xob terminals,
